Mess under the intake? Read this!

[Vivek]

Which hose is it? The only two that really need to be the stock ones (and to be honest they really don't) are the vent from the valve cover and the one that you modify to go from the coolant pipe on the block into the head because it's wider at one end than the other.

[Assassin1710]

would anyone happen to have a picture of the modification done? I took one of these engines apart and one of the hoses got lost and can make sense of it.

Anyone notice after doing this, the heater because extremely hot? I mean if was hot before but damn. Take about 3 mins and its a boiler in my car.

If you think the mess under the intake is bad, this could cheer you up

Ok, good to hear...my car has been well taken care of. Hell, I pulled the valve cover off to paint it and the gasket almost looked new! I ordered the one for the lower manifold to block just to be safe. At least if the center one starts leaking, I won't have to take it all apart again...just the upper!

Split the upper and lower.

You may find as I have that the gasket remains in excellent shape after removing several times. I reassemble with light coat of wheel bearing grease, No issues or vacuum leaks.

Another question, is it necessary to split the lower and upper parts of the manifold, or can I remove the whole thing as one?

Only reason I ask, is because I only ordered the gasket between the lower manifold and the motor.

Yep, splitting is a must. Start with taking the TB off, remove the lines for the heater plates (cut them if deleting the plates, but not if you live in CA, you might want to keep them), and then take off the upper manifold to get to the lower.

Don't worry, I didn't take the diagram question as a criticism. But I will get around to editing it so as not make life confusing.

I believe so. I didn't see an easy way to remove the lower half with the upper still attached.

No worries, I wasn't trying to point fingers...I just don't want to route anything wrong or remove something that needs to stay.

LOL! I used to have a couple of FC's...I've delt with it and it made me want to punch a small child in the throat.

Because of that, I'll be doing this to my 318.

Could someone possibly change the blue and purple colors? They blend to me and I can't differentiate them.

I will get on the color change as soon as I can. Pardon the color issues, initially it was only intended for personal reference. FYI the purple lines only exist between the water pipe and red U/vac hose combo and the heater plates to cylinder head (where the teal line is).

Although I must say, unless you've ever worked on an RX7, you haven't seen a TRUE "mess under the intake."

Hey guys Im having serious issues with my 91' 318is, Ive done over 50 cumulative hours of research over the last couple weeks and just cant figure it out.

FD3S RX-7? No bueno... I don't recall my FC turbo being nearly as bad.
